Not quite woodworking, but how do you cut plexiglass? Would a jigsaw do it?
Can plexiglass or acrylic be cut on a router? Would that take a special bit?

You can cut it on your table/radial arm saw with a fine tooth blade or on a band saw.
You can cut lexan this way too

I had good luck, after trying various blades, by putting in an old dull metal cutting blade in my band saw. Have had decent luck with the router too, slow the speed down to avoid melting the plexi or acrylic material.
Hope this helps........

Suggest a fine tooth band saw blade. Another suggestion leave the backing paper on till completing the cut. Some times helps to use masking tape along the cut line.

Drick, You can get a very clean cut on Plexiglas using your router. No special bit is required. Any single direction saw with fine teeth will cut Plexiglas too. Avoid trying a recipricating blade saw, this will almost always end up cracking your piece.

Just cut some Lexan last night and I used a combination of router, scroll saw and table saw. With the right blades, it cut perfect.

I have cut irregular shapes with a scroll saw. If I am cutting rectangular shapes, I just score it with a utility knife and snap it in to. Works for me.

I asked that question at a woodworking show. The answer I got was to place duct tape on the bottom of the cutline. It keeps the plastic from melting back together. I've done this a lot now on my scrollsaw and with a jig saw. Blade or speed don't matter too much.

The tablesaw blade that we use at the shop has a negative rake on it to keep from chipping out the plexi. when I am cutting oversize pieces I use a router and a guide.
Use a carbide router bit.
